Well, that's the highly informative description from the BBC

"It's based on an entirely new device called a Faraday Exchanger," he says.
It is a large grey cabinet run from a computer display.
"The Faraday Exchanger is able to control voltage, frequency, power factor and balance across phases.
"We have an electromagnetic device and a control system that allows us to control the power flow through the device without using electronic circuits, which is very expensive at higher power levels and introduces noise into the system."
A close look at the video shows it's a circuit simulation - I don't know if there's any footage anywhere of one in actual live use (or what's inside the box).
You could read the several patents so far published. FTAOD I haven't as I'm confident I wouldn't understand them even if I managed to decode the legal language :(
What the article does suggest is that when small scale distributed power generation from individual wind turbines and solar panels is input to the distribution grid it "pollutes" the electricity from large scale generation and makes the distribution less efficient. There must be a point when renewables are producing a smaller percentage of the total demand it would be better to turn them all off in order improve distribution efficiency and reduce costs to the consumer. On the other hand someone has to pay for the 400,000 new jobs!
Correct. That happens. Not sure if it is what the artucles said..
There must be a
Its when reneables are a large proportion of the grid that problems happen.
1/. Excessive payments to reneable companies raise electricity prices
2/. Prefentila take up of reneables penalises efficient gas turbine generation which can no longer cover its running costs out of large negerationg hours, so it tends to hacve to raise its prices
3/. As a result of 2/. gas efficiencies drop as gas is used to balance espcailly solar. Rapid ramping burns more gas.
3/. As a result of 2/. and 3/. CCGT - efficient gas tuirbines - get less profitable and cannot cover their capital and maintenance costs with respect to say diesel and OCGT. Thes are cheaper to build, but are fine to cover short term capacity peaks weher te price of elecetrity ois so high the price of the extra fuel they consume is fairly irrleveant.
The net result of the above is to ensure that wind and solar result in no actual overall fossil fuel savings.
4/. high peak to mean ratios on transmission lines used to carry intermittent renewable energy from where it's generated - say Scotland - to where it's needed - say Manchester - mena that te Grid needs to waste maony on lines taht are oin average scarcely usrtilised or it has to pay reneablke energy sources toi curtauil their outout whenb trhere is e.g. too much wind.
5/. The rotating masses of all the spinning steam and gas and water turbines coupled to the spinning masses of the alternators provides excellent short term stability of voltage and frequency on the grid. It reperesents storage of a sort that can be tapped to provide short term stability. Renewable enbergy is fed via inverters and has no ability to do this, which makes for yet another problem.
Almost none of these costs and problems are borne by the renewable energy companies.
You pay for them in your electricity bills though, as you would pay for the 400,000 salaries in Corbyns renewable revival.
£1000 quid a year for every household for the privilege of creating an unstable grid that doesnt reduce carbon emissions.

It would be of interest to test the device calorimetrically, by running it and a cooling loop inside a thermally-closed container and thereby determin ing its true power loss - doing that by electrically/electronically measuri ng the input and output powers would not be entirely foolproof.
